Tool Wear Analysis While Creating Blind Holes on Float Glass Using Conventional Drilling: A Multi-shaped Tools Study
The present work is focused on the creation of blind holes on float glass using CNC conventional drilling (CD) by deploying multi-shape of tools. The selected tools are listed as a hollow abrasive tool, pinpointed conical tool, flat cylindrical tools, and concave circular tool. The experimental trials are performed by considering industrial conditions. The weight of the tools is estimated in two cases, i.e., fresh tool and after CD process to analyze the overall tool wear. Apparently, micrographs are aided to investigate the phenomena of lateral and end face tool wear while creating blind holes at two stages: (a) fresh tool and (b) after CD. Concave circular tool possessed a minimum percentage of weight loss, i.e., 4.92% after CD and is revealed as a most effective tool, which could be used for drilling purpose followed by the hollow abrasive tool.
